Answer this question truthfully
### Question: What are the symptoms of Complex regional pain syndrome?
### Response: The key symptom is pain that:
Is intense and burning, and is much stronger than would be expected for the type of injury that occurred Gets worse, rather than better over time Begins at the point of injury, but often spreads to the whole limb, or to the arm or leg on the opposite side of the body
In most cases, CRPS has three stages. However, CRPS does not always follow this pattern. Some people develop severe symptoms almost right away. Others stay in the first stage.
Stage 1 (lasts 1 - 3 months):
Changes in skin temperature, switching between warm or cold Faster growth of nails and hair Muscle spasms and joint pain Severe burning, aching pain that worsens with the slightest touch or breeze Skin that slowly becomes blotchy, purple, pale, or red; thin and shiny; swollen; more sweaty
Stage 2 (lasts 3 - 6 months):
Continued changes in the skin Nails that are cracked and break more easily Pain that is becoming worse Slower hair growth Stiff joints and weak muscles
Stage 3 (irreversible changes can be seen)
Limited movement in limb because of tightened muscles and tendons (contracture) Muscle wasting Pain in the entire limb
If pain and other symptoms are severe or long-lasting, many people may experience depression or anxiety.
